![]() NVIDIA engineers already had confirmed that the DMA-BUF passing support will be in place for this major driver series. ![]() The next major NVIDIA driver series, the 470 release series, is slated to be “even more Wayland-friendly” but what all that encompasses remains to be seen. NVIDIA 470 Linux Driver Series To Be “Even More Wayland-Friendly”.And many of those consequences could have been avoided by waiting for the code to enter production status in the first place. Linux kernel release candidates are usually very, very solid, and it’s tempting to dive into new features as early as possible-but doing so can have very, very ugly consequences. This also leads into one of my own rather frequent warnings to fellow Linux users: don’t blindly leap ahead into cowboy code that hasn’t yet been sufficiently tested. This means overwriting not only data in existing files, but also rather large chunks of metadata whose corruption would likely render the entire filesystem unmountable and unusable. If your imagination is insufficient, this means that when the kernel paged contents of memory out to disk, the data would land on random parts of the same disk and partition the swapfile lived on… not as files, mind you, but as garbage spewed directly to raw sectors on the disk. Again, in Torvalds’ own words, “swapping still happened, but it happened to the wrong part of the filesystem, with the obvious catastrophic end results.” Specifically, the updated code would lose the proper offset pointing to the beginning of the swapfile. Torvalds warns the world: Don’t use the Linux 5.12-rc1 kernelĪs it turns out, when Linus Torvalds flags some code dontuse, he really means it-the problem with this 5.12 release candidate broke swapfile handling in a very unpleasant way.In addition the following firmware pkgs have been updated: ![]() You may want to revert to a previous kernel if you’ve already upgraded to Linux 5.12 rc1. Linus Torvalds has renamed Linux 5.12-rc1 to 5.12-rc1-dontuse in git and the release has been pulled from due to an extremely unfortunate bug related to swap files, not swap partitions, that could cause random files to be overwritten with garbage data.
